IMPROVEMENT IN SAWlNG-MACYHINES.

Specification forming part of Letters Paten-t No. 131,510, datedSeptember 24, 1872.

To all whom it may concern:

Be it known that I, JAMns A. ELsroN, of Elston Station, county of Gole,State of Missouri, have invented certain Improvements inSawing-Machines, of which the following is a specification:

The object of my invention is to construct and provide a machine forsawing wood, which is simple and cheap in construction, not liable toget out of order, and will do the work required in an easier and moresatisfactory manner than the heretobefore used and inventedsawing-machines.

In order to describe my invention more fully I will refer to theaccompanying drawing formin g part of this specification.

Figure I is a side view of a sawing-machine embodying my invention. Fig.II is a plan view of the same.

A is a frame, having four legs, B, O, D, and E. On the top of the frameA is placed the upright journal-box F and the guide G. The hollow shaftH, into which is introduced the saw-handle I, is held upon the uprightbox F, in the bearings of the journals ofthe crank L, by a collar orthimble molded or turned upon the upright box, the crank-journalspassing through this collar. A connecting-rod, K, is placed between thecrank L and the saw-haudle I, in order to give the saw M, which isplaced on the end of the. saw-handle I, a backward and forward movement,as required for sawing or separating a piece of wood, N, laid in thesaw-benches O and- B. Said piece of wood N is held in the benches by theaid of the toothed bench piece Q, pivoted on the guided in the slot c,also formed in the stand-- ard of the legs B and E. To said lever S ispivoted the connecting-rod d, which is also pivoted to the hollow shaftH. The two wheels T and U, with handles e and f, are fastened to,

the crank-shaft J, and give the required motion to the saw. The twoguide-pins g and 7L are fastened to the saw-handle Iand work in theslots t' and la in order to give a steady motion to the saw.

The operation is simply this: A log of wood being deposited in thesaw-benches O and P, and held therein by aid of the toothed benchpiece Qand the lever It, is operated upon by the saw M, which is lifted, by aidof the lever S before the sawing, in order to introduce the log in thebenches.

Having thus described my invention, I desire to claim- 4 The frame A,provided with legs B, O, D, and E, saw M, handle I, crank-shaft J,upright journal-box F, wheels T and AU, connecting rod K, crank L, andsaw-benches O and l?, in combination with the upright guide Gr, the

hollow shaft H, bench piece Q, lever S, slot b,

lever B, slot c', and connecting-rod d, substanially as and for thepurpose hereinbefore set orth.
